Question 4 (5 points)

(a) Draw the Lewis structure for the nitrite ion,[1]

(b) Explain, considering hybrid orbital theory, the correct hybridization and shape of the central atom for the nitrite ion, . Upload your handwritten rationale and any appropriate work here. [2]

(c) Explain why sodium nitrite, is a solid and nitrogen dioxide, , is a gas at room temperature. [2] 

Sketch the resonance structures for the nitrite ion, NO₂^-. Describe the electron-pair and electron geometries of the ion. From these geometries, decide on the O-N-O bond angle, the average NO bond order, and the N atom hybridization. 

Sketch the resonance structures for the nitrite ion, NO₂^–. Describe the electron-pair and molecular geometries of the ion. From these geometries, decide on the O—N—O bond angle, the average NO bond order, and the N atom hybridization.
